Sind das lettische Beamte?

So some backstory, a friend and I were sitting in a park in San Francisco when a bunch of security staff and some reporters and this group of 3 individuals come by. 

They blocked off a large section of the park, and proceeded to have an interview, I guess, as they were mostly quiet. When passing by we heard some eastern European language, and when reverse image searching the woman in the photo I got to several Latvian sites but no exact matches for her or for the man. So mainly just curious. 

Their security staff was laughably “security” and just said they were VIPs without any further detail. 

Then I found this: https://business.gov.lv/en/news/latvian-business-delegation-san-francisco-explores-new-avenues-expanding-cooperation-global

But honestly not sure if it’s all related. Could anyone provide any details?
